Hypoxia and hypercapnia · Physiology

Carbon monoxide poisoning causes hypoxia by:

  1. Reducing alveolar ventilation rate
  2. Directly blocking oxygen diffusion
  3. Reducing hemoglobin availability
  4. Increasing tissue oxygen demand markedly
Show answer and explanation

Correct answer: Reducing hemoglobin availability

Carbon monoxide binds hemoglobin with high affinity. This reduces oxygen transport capacity and causes anemic hypoxia.
